Title: Emergency diesel generator set - sync.-async. mode switching using suitable placed relays and contactors
IPC: H02J9/06
Filed: 1973-05-02
Abstract: The emergency supply generator and control system consists of a diesel engine driving a generator coupled to the 220V 50Hz mains network. Failure of the mains network is detected by the absence of voltage or frequency and initiates generator switch-over from synchronous to asynchronous operation. When the supply returns, the generator is switched automatically back to synchronous operation. The switch over is achieved using a series of interdependent relays and contactors, and may also be carried out manually. The low voltage supply is obtained from a battery charged from the mains network.

Title: Direct current generator for welding - with automatic control of triggering of thyristors in rectifying bridge
Inventor: PRISCHI GUIDO
IPC: B23K9/073
Filed: 1976-04-02
Abstract: DC generating method is provided for welding with coated electrodes, in which, after voltage transformation if necessary, AC is rectified by a rectifying bridge with thyristors and a smoothing inductance coil at the output. Triggering of the thyristors is controlled automatically so as to maintain the welding current constant for any voltage below a max., by means of a control voltage of a thyristor trigger circuit, obtd. by picking up a filtered measuring voltage proportional to the welding current, amplifying it, and forming a differential voltage between this and a direct reference voltage of constant amplitude. From the differential voltage is formed a voltage which is the sum of a voltage proportional to the differential voltage and a time-integrated voltage. If required, the potential and amplitude of the resulting voltage are adapted.
